Headmistress' Favorite Sport Part 9

In the month she stayed with Mistress Rachel and Master Tony the times when she sucked Master Tony's cock were the only times she was rewarded. The rest was hard work.

Denise had been utterly shocked when she saw her mother for the first time since returning from the academy. The extent of her degradation was stunning. She barely noticed Denise, her focus being solely on Mistress Rachel. The way in which she savored her role as diapered toilet slave was also a shock to Denise. While Denise had turned into a well-behaved and sexually very sophisticated sissy-slave who was trained to handle almost any slave duty, Susanna had turned into a filthy slut capable of only the simplest of tasks. The sexual tension, which had existed between the two was gone and the only time they had anything to do with each other was when Denise oversaw Susanna and Helen's morning toilette.

After a month the twins were ready to receive Denise as their slave. The house, previously owned by Angela, had now been rebuilt to suit their needs as mistresses and they had had time to start their college educations. Since they used most of their efforts at school no major slave training activities went on at the house. That would come in time. For now Angela, Mandy and Denise were enough. For Denise the change was minimal. She performed the same duties as she had at Mistress Rachel's house, in the same uniform and with same relentless rules. The only difference was the amount of attention her cock received. The twins just loved to play with it. At night when Denise's chores were done, before she was locked in her cage, they would strip her, tie her up and play with her genitals. They freed them and her member always sprang into action instantly. It had been months since Denise had been allowed to cum, but the twins were not about to change that. No, all they wanted to do was to keep Denise right on the edge without allowing her to cum, while subjecting her cock and balls to harsh punishment. Kicking Denise in the groin or trampling her cock and balls with their stilettos were favorites of theirs, as was applying electricity to them. Often Denise's balls would be unbearably swollen when she woke up, but there was no mercy. She had to press them up between her legs so that she had smooth crotch.
